Three of the main traffic light intersections in downtown Darien will be non-functioning for most of the time between 9 and 3 p.m. Thursday according to Darien Police. The reason for the interuption is work being doing by the state Department of Transportation. The intersections with the Post Road at West Avenue, Tokeneke Road and Center Street, seen at the stars in the above map, will be affected. Darien Police issued an advisory Wednesday\u00a0 that traffic in the downtown area will be affected on Thursday, Feb. 8, between the hours of 9 and 3 p.m. Electrical contractors working for the Connecticut Department of Transportation\u00a0 will be working on the controller(s) that operate the traffic signals on US 1 at Center Street, Tokeneke Road and West Ave. \u00a0This will require the traffic signals to be non-functioning during a significant portion of this time.\u00a0 \u00a0 \u00a0 Officers have been assigned to this project to assist with\u00a0 safe and orderly traffic flow through the downtown area during the time that the lights will be non-operational. The contractor has assured town officials that they will work as expeditiously as possible to return the lights to normal operation. Darien Police are asking all motorists plan trips through the downtown area accordingly and consider alternate routes if possible.\u00a0 "We thank you in advance for your cooperation and patience as the traffic signal replacement project moves forward," the advisory said.
